I have a 2002 omega 2.2 automatic.
The EML light has been on and when i took it to a code reader i got the following error codes.
P0141 O2 SENSOR PRESENT. -004 HEATER CIRCUIT OPEN
P0036 HO2S HEATED PRESENT.oXYGEN SENSOR- CONTROL CIRCUIT( BANK 1 SENSOR 2)
P0170 fUEL TRIM . NOT PRESENT- SYSTEM MIXTURE LEAN.
Also though there is no leak on the car cooling system i have been topping up collant at least every 14 days.
I bought both sensor from Vauxhall and they should arrive this week so i just want to know which one to replace.
Thanks.

Thanks rob.
I have noticed the omega fuel consumption has gone up considerably...is this because of the failed sensor?

Consumption will increase. As you`ve now ordered the sensors, once fitted clear the codes. If 0170 returns could be a faulty MAF.
